The copy operator has been implemented and doesn't use it. Remove `Builtin.copy` and `_copy` as much as currently possible. Source compatibility requires that `_copy` remain in the stdlib. It is deprecated here and just uses the copy operator. Handling old swiftinterfaces requires that `Builtin.copy` be defined. Redefine it here as a passthrough--SILGen machinery will produce the necessary copy_addr. rdar://127502242
